Universal Data Mover Manager for UNIX

Overview

This page provides information on the Universal Data Mover (UDM) Manager, specific to the UNIX operating system.

UDM Manager transfers files between any computers running UDM Server. Using a UDM command script, you indicate to the UDM Manager the actions to take. The UDM Manager connects to the UDM Server (or Servers) and processes your request.

Usage

UDM Manager is executed from the command line (interactive mode) or a script (batch mode). In interactive mode, commands come from standard input; in batch mode, they come from a script file.

This section describes the modes of operation, configuration and configuration options, and command line syntax of UDM Manager for UNIX.

Modes of Operation

Under UNIX, UDM can be run either in:

  • Interactive mode
  • Batch mode

Running UDM in Interactive Mode

To run UDM in interactive mode, enter the following at the command prompt:

udm

This starts the UDM Manager. You will be greeted with a start-up message and the UDM prompt:

UNV2800I Universal Data Mover 6.3.0 Level 0 started.

udm>

UDM now is ready to process commands. At the udm> prompt, you can enter any UDM command.

To exit UDM, enter the following command at the udm> prompt:

quit

Running UDM in Batch Mode

To run UDM in batch mode, enter udm on the command line and specify a script file via the SCRIPT_FILE option.

For example:

udm -script script_filename

When the script file has finished executing, UDM exits automatically.

Configuration

Configuration consists of:

  • Setting default options and preferences for all executions of UDM Manager.
  • Setting options and preferences for a single execution of UDM Manager.

Configuration options are read from the following sources:

  1. Command line
  2. Command file
  3. Environment variables
  4. Configuration file

The order of precedence is the same as the list above; command line options being the highest and configuration file being the lowest. That is, options specified via the command line override options specified via a command file, and so on.

See Configuration Management for detailed information on these methods of configuration.

Configuration File

The configuration file, udm.conf, provides the simplest method of specifying configuration options whose values will not change with each command invocation. These default values are used if the options are not read from one or more other sources. (See the Universal Agent 7.6.x Installation, Upgrade, and Applying Maintenance to determine the directory in which it is located.)

Some options only can be specified in the configuration file; they have no corresponding command line equivalent. Other options cannot be specified in the configuration file; they must be specified via one or more other sources for a single execution of UDM Manager.

Configuration Options

The following table describes the configuration options used to execute UDM Manager for UNIX. Each Option Name is a link to detailed information about that configuration option.
